A lot of emails received today contain affected zip files

The server scans attachments but only up to a certain size, otherwise the server will slow right down. Hackers normally send through other infected computers sending larger attachments.

You can set a filter in CPANEL under the email section to get rid of these. Choose either Global to apply for all emails or Email filters if you want to select individual emails.

Select Create a Filter

Give the filter a name

Choose Body

Contains

enter .zip to discard any emails with a zip attachment

Actions – I would select Discard Message – that’s up to you.

Update

1/12/2016 We have had to force a ban on emails containing attachments of certain file types. This applies to sent and received emails. Right now there are huge volumes of emails to random email addresses usually containing large attachments with hidden Malware. Some of these hit the right spot, most emails are bounced as the return to address does not exist.

Technically is it up you to block what you don’t require using CPANEL. For some of you doing that it’s much appreciated.

Right now we have to take action to protect server loads. We will remove the block once we shift to a new server, then monitor loads again.

if you want to send an email with an attachment which is blocked please do the following:- Rename the file to say .pdf extension.Example: Sending a zip attachment Rename the .zip file to .pdf Explain to the person receiving the email to rename the email back to a .zip extension
